Diversity and composition of macroinvertebrate in floodplain lakes of North Bihar, India


Author(s): AK Singh, Rani Kumari and Arun Kumar

Abstract: The benthic macroinvertebrate fauna and physico-chemical parameters in floodplain lakes were studied monthly from September, 2012 to August, 2013. The investigated lakes, Tarawe chaur and Gamharia chaur are located in district Madhepura of north Bihar, India between 25°34ʹN to 26°07'N latitude and 86°19'E to 87°07'E longitude. In total, 26 species belonging to 17 genera and 17 families were recorded. Benthic macroinvertebrate communities consist of Oligochaeta, Hirudinea, Insecta, Pelecypoda and Gastropoda. Number of species was highest in clean-water environments at Tarawe chaur (21 species) than in poor-water quality at Gamharia chaur (15 species) where sewage disposal eliminate pollution-sensitive species. However, the population density of benthic fauna was highest in poor-water conditions at Gamharia chaur than in clean-water environments at Tarawe chaur. Gastropod was the most abundant group (12 species) followed by pelecypod (5 species), insect (1 larva and 3 nymphs), oligochaete (3 species) and hirudinea (2 genera). Of these, 10 benthic macroinvertebrate species were common. Variations in the abundance of total macroinvertebrate and the species in it were clearly influenced by water quality. Highest percentage of Sørensen’s similarities for total macroinvertebrate and its groups revealed more homogeneity between species in communities, while dissimilarities showed minor differences between species in communities probably due to habitat heterogeneity.
